The 2015 guide has been revised by Jonathan Wyner, iZotope’s education director and the chief mastering engineer and founder of M Works Mastering Studios, where his mastering credits include David Bowie, Cream, Nirvana and Aerosmith.

“Mastering with Ozone is part of iZotope’s initiative to give back to the audio community,” the audio technology company said in a statement. “Over the past decade, they have compiled knowledge and feedback from mastering pros into a guide that’s useful for users of all levels.

“It’s the perfect educational companion to [mastering software] Ozone 6 and Ozone 6 Advanced for users who want to learn more about the powerful polishing tools available in the latest version of iZotope’s acclaimed mastering suite. But it’s also designed to be helpful for all audio enthusiasts, whether or not they own iZotope’s creative mastering platform.”
